Looking for 2 things if you can help: 1. While the 330/84 TR WSM indicates a SANKYO AC Compressor is used on TRs, mine's got a Sanden SD-508 Model No. 9295 (which matches the SANKYO WSM illustrations perfectly) -- Could you check the nameplate on top of your AC Compressor and post which Brand & Model No. (if present -- and don't worry about Serial no. if shown)? 2. There's a disagreement in the relative position of the heat exchanger built into the RH fuel tank between the TR OM 634/90 illustrations and the words describing the AC hoses in the TR SPC 587/90 (interestingly, the SPC illustrations actually agree with the OM illustration so they don't match the SPC wording either). My guess is the SPC words are wrong, but I want to confirm that (without hassling to check on my own TR) so the question is: Is the short hose going from the AC Compressor to the fuel tank heat exchanger hooked up to the DISCHARGE or SUCTION port on the AC Compressor head? ("DIS" and "SUC" labels should be shown on the back of the AC compressor head.) TIA for any help, Steve M.
